I have an SR open with support at sev2. They haven't touched it in 5 days. As for vgcreate, et....My unix admins handled that aspect, and I assume they did the right thing, although I am somewhat suspect of their actions. The AIX install guide has a number of hoops to jump though(because AIX sucks). One of the steps is a mknod on each node if the device file names are not the same.
